I recently set up Asterisk with an Adtran TA750. All is well except the phones do not show the MWI. I have configured zapata.conf properly, as all phones will receive a stutter dial tone if there is a message waiting in it's assigned mailbox. Does anybody know how I might fix this problem? Thank you for your time ________________________...

All, I need help. I have an (actually 2) Adtran TA750's with 8 FXO ports. I get a terrible buzz on every FXO port. If I unplug the Adtran and put an analog phone on each incoming line, I have no buzz. I also have 2 Carrier Access Access Bank I's with 12 FXO ports. When I plug the same analog lines into either one of those, no noise or buzz wha...

Rich, Thanks a bunch, totally understand now and that actually makes total sense. (no need for schematics). This also explains why I used an TA750 to go into a Nortel MICS system, using FXO and no buzz. Totally balanced load from the analog ports on the Nortel across the 5 feet of CAT5 to the FXO on the adtran. Now I need to get rid of some Adtrans --- Anyone lookin to buy? :) Thanks again.............Greg Gregory P. Scasny Golden Techno...

Hello. I have been going thru the wiki and asterisk related sites and have not been able to find any documentation about how to configure an Adtran TA750 channel bank. The remote disconnect supervision doesn't seem to be working, when the remote caller hangs up asterisk takes up to 30-45 seconds to hangup the call. Can somebody help? Thank's

...y extra work I've put you through. Posting from my work account, as proper) Hello all, I'm back. I've got that lucky feeling that this will all work out very soon, and I hope that that is true. The issue: In my * server I have a t100P, connected with a T1 crossover cable to an Adtran TA750 with 2 FXO cards. After I do 'modprobe wct1xxp;ztcfg' the alarm on the card starts blinking red. running zttool confirmed that yes, it is a red alarm. I've read a few previous posts on this type of setup and I'm not too much closer. What should I be checking next? A different cable?...

Hello all, I've got a T100P connected to an Adtran TA750 with a T1 crossover... This connects to a patch panel with phone ports. The Adtran is fully populated with FXS cards. All I get on any phone port is a fast clicking noise... No dialtone. Asterisk 'sees' the card, (the channels show up in /proc/zaptel). Incoming calls are routed to the...

...d Telco will return to an idle condition by opening their switch. The call can also be terminated from the telco side if the incoming caller hangs up. When this happens, the telco opens their switch and loop current stops flowing. The PBX then returns to an idle condition. My PBX communicates with TA750 on T1 with T100p card. I don't know what signaling needs to be set in Zaptel.conf and Zapata.conf files, so that once Telco send the signal it will see the PBX and rings that DID extensions. Has anyone had done this? Please let me know, I have to put this machine live by Monday and I stuck w...

Hello, So all the pieces are finally here, and I'm ready to play. I remember reading on this list that the connection Channel Bank <-> T100P requires a "reverse cable." Is this a regular Ethernet reverse cable (i.e., only a couple of pairs reversed?) Please help me before I blow something up! Saludos, Jose.

Folks, I recently obtained a Western Electric multi-line phone and am seeking help with getting this beast working with *. The interesting stuff in my * implementation consists of a T100P card, a TDM400P card, and an Adtran TA750 channel bank with three quad-port FXS modules and a quad-port FXO. The TA750 is wired to a 24-port Cat 5 patch panel via a 25-pair Amp cable. The phone is a model 2662A1M; it has five lines, a hold button (I presume), card dialer capability, and a 25-pair Amp cable for connecting to The Phone Sys...

We currently have a 15-phone system using Asterisk, a combination of analog phones/Grandstream HandyTone-286 and Grandstream BT101s, and 4 X100Ps connected to analog lines. The system works well except for the occasional echo problem. I have all the echo parameters configured, removed all the extra incoming analog lines except to the PBX, etc. following all the advice on the wiki and on the

I get seg. fault with my * box. at the crash time i had about 35 Bridged Channel. i have: - dual xeon box (3.2Ghz) - 2Gb of memory - E7501 chipset motherboard. - U320 scsi disks - intel Gb ethernet device. - i only use sip for clients (no fxs in box) - TE405P for fxo (with 4 atran TA750). - ulaw is used as codec and echo cancellationo is enabled. but the core dump file has nothing to show with "gdb". this is the output of gdb: Program terminated with signal 11, Segmentation fault. #0 0xb7fbbce4 in ??

...out of the picture for me) and I need to validate that traffic (only accept calls coming from his IP). After that I would terminate the calls to the PSTN network and keep logs for billing purposes. -I have a TE405P board and only one T1 worth of phone lines (24) connected to it using an Adtran TA750 channel bank. Is Asterisk capable of handling multiple incoming VoIP calls arriving from the same source (IP) or do I need to get something else to take the incoming traffic and pass it on to Asterisk? (I've read about using SER as a SIP proxy, but it's not clear to me wheather I need i...

Can anyone share any advice / documentation on how to configure a Tellabs 2572 T1 echo canceller? I connected one between a T100P and an Adtran TA750 FXO/FXS channelbank, but when echo cancellation is active I get a LOT of snap-crackle-pop (and other problems) on the line. The 2572 has a bunch of configuration options and they're impossible to guess without documentation, which I cannot find anywhere. I've registered for the Tellabs po...

I've tried this before, with no luck. I've got to try again this evening, and I'm looking for some help. Here's my configuration -- pretty simple, really. Asterisk box -> T100P -> TA750(20FXS/4FXO) -> phones and outgoing lines I have an analog modem (Ok, it's a TIVO) that I need to be able to dial out. Right now, I have the modem connected directly to an outgoing line that asterisk is also connected to. As long as the line's not in use, the modem can pick it up and u...
